Hi, I have some info on my imac that I put on a 4gb Sandisk memory stick so I can transfer the files to a PC at work. The PC at work does not detect the USB memory stick at all. Tried in 4 different PC's and none of them detected it. The orange light on the memory stick doesn't light up when inserted to a PC. I put the memory stick back in my imac and it is fine, same with my macbook. Memory stick was formatted on Imac to MS-DOS(FAT32) before files were added to it. Any ideas why PC's are not detecting this memory stick?
